[Fixed] Difficult to find error

Bug Reports

When I run my minimalist app, I get this :

New session: 19/11/2023, 22:46:09

ModuleNotFoundError: No module named 'None'

Not all modules are available in client code. Click for more info

How do I work out where the error is?

The app is just a portable class definition, nothing else. It’s designed purely to be included as a dependency.

I originally got the error in an app that included it as a dependency, but I get the same error if I just run the app directly. If that makes any sense?

This is the class :

import anvil.server

@anvil.server.portable_class("_Response")
class Response:
    def __init__(self, status=999, data="", text=""):
        self._status = status
        self._data = data
        self._text = text

    @property
    def status(self):
        return self._status

    @property
    def data(self):
        return self._data

    @property
    def text(self):
        return self._text

The class is a WIP and just a placeholder really, but it works when included as part of the code in other apps (ie not as a dependency).

Ok, it appears I have to have a client side form or module (set as Start Up). I’m pretty sure this didn’t used to be the case, but it seems to work if I just create a module & set it as the start up module. So maybe it was always like that…

Thanks for reporting, we’ll get that error message fixed
